Hw-044 Datasheet

The HW-044 is a USB-to-UART (Universal Asynchronous Receiver-Transmitter) converter module. It's a small electronic component that enables communication between a computer and a microcontroller or other devices that use UART communication protocols. The HW-044 is widely used in robotics, automation, and IoT projects.

The module typically features a 3-pin header for control and a 3-pin terminal block for the load.

The module typically features two sides of pins for interfacing: TTL Side (Connect to Microcontroller) Power input (3.0V - 5.5V). GND: Ground. TXD: Transmit data (connects to MCU RX). RXD: Receive data (connects to MCU TX). RS-232 Side (Connect to PC/Serial Device) VCC/GND: Shared with the TTL side. TXD: RS-232 Transmit. RXD: RS-232 Receive.
